It sounds like a significant hindrance is picking out voices in crowds, and making one's own voice heard in the crowd, as a result of the poor microphone / speakers on the iPad. With the great big self-balancing stick peripheral, it's a wonder that they've not thought to attach a pair of microphones with binaural software onto the double (so you can hear if someone is talking behind you, to the right, etc). Then the user at the other end could put on some headphones and pick up everything that's going on around them. Binaural audio feedback also greatly enhances immersion. Surely a slightly larger / louder speaker wouldn't cost too much either?
